You may not have enough angle to bank it in that corner AND send the cueball around the table.  Your shot is going to be a bit table-specific.  If you're on new cloth that slides or slow cloth, you might not be able to get the cueball to move.  If that's the case, in my opinion, it's not worth making the 8.
I would sooner bank it into the same corner I'm shooting out of.  Still, the fact that I'm shooting from a place where cueing remains an issue still makes this terribly problematic.  The precise location of the cueball makes a difference here.  I'm going to need to cue-up just right and if I can't, that could change everything.
